Q341.Which of the following is NOT an output device of a computer?
Correct Answer: D
Keyboards, mice, and scanners are all classified as input devices because they feed data into the computer.
Q342.Which of the following is classified as a secondary storage device?
Correct Answer: D
Hard disks and CD-ROMs are non-volatile secondary storage media. RAM and ROM are primary memory.
Q343.The process of moving data between secondary memory (Hard Disk/SSD) and primary memory (RAM) is known as the ______?
Correct Answer: B
The Transfer Method refers to the input/output operations that move bytes between long-term storage and volatile RAM.
Q344.The ALU (Arithmetic Logic Unit) and CU (Control Unit) are core sub-components of the ______?
Correct Answer: B
The CPU (Central Processing Unit) houses the ALU (calculation processing) and the Control Unit (operation coordination).
Q345.The primary computational and processing block inside a CPU is the _____?
Correct Answer: A
The ALU (Arithmetic Logic Unit) executes all logical, comparison, and mathematical operations inside the CPU.
Q346.A physical hardware device used to modulate and demodulate signals is connected to a _____?
Correct Answer: A
A MODEM connects a computer network to an external analog communication medium, such as a physical telephone line.
Q347.The classic, heavy output monitors and television displays used which technology?
Correct Answer: C
CRT stands for Cathode Ray Tube, which utilizes an electron gun to project images onto a phosphorescent screen.
Q348.What is the non-volatile memory built directly into the computer's motherboard called?
Correct Answer: B
ROM (Read-Only Memory) is permanent, non-volatile memory that stores boot instructions (BIOS) written during manufacturing.
Q349.The core hardware architecture of a CPU consists of which basic components?
Correct Answer: D
A standard CPU integrates an ALU (processing), Control Unit (coordination), Registers (storage), Cache, and Internal Buses.
Q350.The computer's volatile main memory, such as RAM, is also formally referred to as ______?
Correct Answer: D
Primary Storage, Primary Memory, Internal Memory, and RAM are all equivalent terms for a computer's volatile main memory.
Q351.What does the hardware connection standard SATA stand for?
Correct Answer: B
SATA stands for Serial Advanced Technology Attachment, an interface standard for connecting storage drives (HDDs/SSDs) to the motherboard.
Q352.Where is the startup firmware BIOS typically stored on a computer's motherboard?
Correct Answer: C
The BIOS is stored in a non-volatile flash memory chip (ROM) on the motherboard, preserving startup configurations.
Q353.Which of the following is classified as non-volatile computer memory?
Correct Answer: D
ROM and PROM are non-volatile memories that retain written data when powered down. RAM is completely volatile.
Q354.A computer's central CPU is classified as which of the following?
Correct Answer: A
The CPU (Central Processing Unit) is a physical, silicon-based hardware processor component.
Q355.Which basic clipboard operation removes text from a document and holds it temporarily on the system clipboard?
Correct Answer: B
The Cut command deletes selected content from its active position and holds it on the clipboard for relocation (pasting).
Q356.Which component of a computer is responsible for processing and executing instructions?
Correct Answer: B
The CPU (Central Processing Unit) is the main microprocessor responsible for fetching, decoding, and executing program instructions.
Q357.What is the primary purpose of a motherboard in a computer system?
Correct Answer: A
The motherboard acts as the central printed circuit board that connects all critical hardware (CPU, RAM, drives) and allows them to communicate.
Q358.What is the process of data copying from a server to a personal computer called?
Correct Answer: D
Downloading represents the process of transferring and copying files from a remote web server onto a local personal computer.
Q359.Which memory type is known for having the longest access time among early non-volatile memories?
Correct Answer: D
Magnetic Bubble Memory, developed in the 1970s, utilized serialized shift-register bubble loops, leading to longer access times than solid-state RAM.
Q360.Which component gives power supply to a computer?
Correct Answer: B
The Power Supply Unit (PSU) converts alternating current (AC) electricity from wall outlets into direct current (DC) power required by computer hardware.
